UCC28950 bidirectional use

Other Parts Discussed in Thread: UCC28950

Hello,

I wanted to ask if it is possible to implement a bidirectional controller with the UCC28950.

If not I would be very interested, if there is any other chip for this application?

Thanks in advance!

Best Regards

Uli Bürger

    I don’t believe that anyone has tried to use this device in a bidirectional topology.

    What typical controllers are used in bidirectional topology?

    Regards,

    Perhaps I should dicribe a little bit more in detail what I want to do:

    I have a high voltage battery and a high voltage DC-supply and I want to transfer energy between the battery and the DC supply (charge and discharge).

    The battery-voltage is in full state round about 300 V and in empty state round about 200 V and the DC supply has a typical voltage of round about 330 to 350 V.

    A typical application for bidirectional DC-DC-Converters with pretty similar in- and output datasets is the use in an electric car for driving the motor or to put the brakeenergy back into the battery.
